SEAM FOR SEWED FABRICS.

SEEGIFICATION forming part of Letters Patent No. 540,62*?, dated June 11, 189 5.

Application eea July 26,1894.

To all whom it may concern/ Be it known that I, CHARLES E. BENTLEY, a citizen of the United States, residing at the city of New York, county and State of New York, have invented a new and Improved Seam for Sewed Fabrics, of which the following is a specification.

My invention relates to a novel seam for sewed fabrics, andv has for its object to provide an ornamental seam of this general character formed with a foundation fabric and threads held thereto and'so interlocked with each other that the seam will not unravel and cannot be easily ripped out by pulling the threads.V A

In the accompanying drawings similar numerals indicate like parts in all the views.

Figure 1 shows my seam as it appears at the upper face of the fabric. Fig. 2 shows the seam at the lower face of the fabric. Fig. 3 is a transverse section on the line a: Qc in Fig. 1. Fig. 4 is a longitudinal section along the purled edge of the seam and taken on the line y y in Fig. 1. Fig. 5 is a perspective view illustrating use of the invention for overseaming, as when making buttonholes, dac.; and Figs. 6 and 7 show two of many different forms of scalloped embroidery seams which may be produced.

My improved seam comprises th ree threads 1, 2, 3, worked on and through a foundationv fabric 4. The upper thread 1, is carried by a needle. The lower thread 2, is a shuttle thread, and the thread 3, is the main ornamental thread of the seam and is carried by a second needle. The thread 3, is looped through the foundation fabric'at one edge of the seam, and is also looped transversely upon both upper and lower faces of the fabric to the second or oppositev edge of the seam by p looper devices which may have any suitable construction and need not be described." At the second or opposite edge of the seam the threads 1, 2, are interlocked with each other after passing respectively through the upper and lowerloops of the main thread.

We will suppose the thread 3, is looped by its needle through the fabric 4, at 5. The looper devices now catch this thread and loop it transversely or sidewise upon both upper and lower faces of the fabric 4, tb the opposite edge of the seam, The needle carrying Serial No, 518,615. (No model.)

Athe upper thread 1, .nowloops this thread either through the foundation fabric or past an Aedge thereof, and within the bends or turns 6, 6, of the two lateral upper and lower loops of the thread 3, at the second edge ot' the seam. The shuttle thread 2, is now carried through the loop of thread`1, below the lfabric 4, and when the needle carrying the thread 1, next rises and the threads 1, 2, have proper tension, these two threads will be securely interlocked with each other through the loops 0f the main ornamenting thread 3. Successive stitches made in this manner, produce a seam which has a purled edge along the threads 1, 2, next the bends 6, of the loops of the main thread 3, at both upper and lower faces of the fabric 4, and the finished seam has substantially the same ornamental appearance at opposite faces of the foundation fabric, all as clearly shownin the drawings.

The second purled edge of the seam may be worked at'anydesired distance from the edge of the foundation fabric 4, as shown in Figs. 1 to 4, of the drawings, or said purled edge of the seam may be worked outside the edge of the fabric as a binding therefor, in the manner knownA as overseaming, as when making button holes, dac., and as illustrated in Fig. 5, of the drawings.

By making the thread carrying needle or needles adjustable laterally to vary the length of the transverse loops of the thread 3, embroidery scallops of various designs may be worked on thefoundation fabric; examples being shown in Figs. 6 and 7, of the drawings.

My improved seam differs from other seams of like general character by having the two threads l, 2, passed through the upper and lower loops of the main thread 3, and interlocked with each other like the needle and shuttle threads of an ordinary lock-stitch sewing machine, whereby the transverse loops of the thread 3, are securely held by the locked stitches of the threads 1, 2, thus preventing the seam from being ripped out or unraveled by pulling the threads. l

I claim as my invention- The improved seam for sewed fabrics, com- IOO prisin g one or more thicknesses of fabric and three threads 1, 2, 3, combined therewith; the

cessive stitches and looped transversely from one'strand of said loop and then ce out through Io said points of passage on both upper and the loop of thread 3, on the lower face of the lower faces of the fabric tothe opposite edge fabric, whereby threads 1, and 2, are interof the seam, a loop of thread 1, being passed locked through the loops of thread 3, sub- 5 through each loop of thread 3, on the upper stantially as described.
